Langflow Runner

Runs Langflow flows using as input a selected column and returns the output. Langflow is called iteratively, one row at a time. It supports parallel execution of calls (concurrence).

This component enables an integration of Flowise flows (multi-LLM, Langchain orchestration) into KNIME workflows.

You need to specify the Langflow server to call, the flow ID, and the Langflow API key.

You will find the Langflow server and flow ID in the API Panel in any Langflow flow, while the Langflow API key needs to be generated in Langflow settings.
